That's what I tried already. It simply echoes the ^Z (right arrow). I tried also to close the pipe explicitly from the sender side without success: mProcess.CloseInput; CloseHandle(mProcess.Input.Handle);
I'm afraid we're looking at a problem with more.com waiting until the process releases the pipe. Closing the handle from one side of the pipe isn't enough to close the pipe. Or as http://msdn.microsoft.com/en-us/library/aa365152%28v=vs.85%29.aspx says: "An instance of a pipe is always deleted when the last handle to the instance of the named pipe is closed".
